When a block is placed above the void with no other blocks near the area of 0 0 0, it freezes for a second.
It seems to stop happening farther away it doesn't seem to do much frame drops. It seems to only happen when the block is surrounded on all 4 sides.
Here's a video showing the bug as explaining it is harder.
Update #1: It seems that pistons also do the same thing but they have weird activity (The same with hand placed blocks)
A list of blocks where the lag spike doesn't happen:
These are all the blocks I could place without commands. Mostly they're the transparent ones. Weird that a Enchantment Table is here but not the Farmland or Path blocks. Is it because the Enchantment Table has a animated book on it and causes particles?
